Download Brother drivers

First create a temporary directory. Download the lpr driver and cupswrapper driver rpm files from Brother's website.
The full list of brother linux drivers can be found here and these instructions can be followed for other printers as well as the MFC-9320CW.

Extracting the RPM files

Now you use a small script called rpmextract which allows you to get the files included in the RPM you've just downloaded.
Extract both RPM files :

Installing the driver and printer

It will stop the cups daemon if it's running, and restart it.
Now go to the CUPS page : http://localhost:631/
In the Administration category, choose Manage printers. There you should see a MFC-9320CW printer automatically installed and configured. It is intially configured to use the USB port.
If the printer is used as a network printer you need to modify the printer configuration. Choose Modify printer, and select Brother MFC-9320CW in the device list. If it doesn't exist choose LPD/LPR Host or Printer instead. Then in Device URI you enter the printer IP, e.g lpd://10.0.0.10. You will find the IP address in the LAN configuration on the printer itself. The rest of the configuration is preset, so just choose continue.
Click to print the test page, and you can hear the sweet sound of your printer. If not, try to restart your printer, and make sure the printer's state is Idle, accepting jobs.
